someblubb.h
Code:
class CBlubb {
  void Blubbba();
}
someblubb.cpp
Code:
inline void CBlubb::Blubbba() {
  Blob();
}

So that would inline Blubbba if possible and if not, give me a warning about it, right?

btw, is it right that I can't have inlines in an abstract baseclass (of course not for abstract functions, but for functions that use abstract ones) ? If I inline those, the compiler always tells me it can't find an implmentation for *functionname*.
